Answer:
Step-by-step explanation:
Using either the critical value rule or the p-value rule, a conclusion can be drawn at a level of significance (alpha)
The null hypothesis: u = hypothesized mean
Alternative hypothesis: u > u0 or u < u0 for a one tailed test
Alternative hypothesis for a two tailed test: u =/ u0
To draw a conclusion by failing to reject the null hypothesis as stated then: using critical value
Observed z score > critical z score for both the one and two tailed test.
Or using p value:
P-value > alpha for a one tailed test
P-value > alpha/2 for a two tailed test
Thus, if a one-sided null hypothesis for a single mean cannot be rejected at a given significance level, then the corresponding two-sided null hypothesis will also not be rejected at the same significance level.
Answer:
There is no equals sign in that expression so it is not actually an equation and has no solution.
If you are looking to expand the two polynomials, then you get:
(x² - x + 5)(x - 3)
= x(x² - x + 5) - 3(x² - x + 5)
= x³ - x² + 5x - 3x² + 3x - 15
= x³ - 4x² + 8x - 15

All u have to do is divide 5by 720 and u have ur answer
Answer:
a. stretched by a factor of 2 and translated 64 units right and 5 units down
Step-by-step explanation:
took the test
Y=1x-90
-90 is the y-intercept and you get 1x because it rises 10 and runs 10.
10/10 is 1.
